My one problem with this story is that the main tension (Minnie Driver's hesitancy to tell her beau that she's had a heart transplant) doesn't seem motivated. The whole time we know that Minnie Driver doesn't want to tell him about her heart so she keeps lying and wearing high-neck shirts to cover her scar and her secret. Seeing this from a screenwriting point of view, I didn't understand why it was such a big deal that she keep it a secret.
I would use this film in a classroom setting in order to open a discussion about the story structure and the tension. I think that people would disagree with my analysis, which would open great lines of communication regarding the subjectivity of everyone's viewing experience as well as allowing students to both express their opinions as well as learning from others regarding what makes a good story.
